    ChangeLog

    0.4.0

    1. Remove multi-line prefix (v0.3.1) for the sake of efficiency
    2. User can define any color of the message by .(color) format, but it only works after the :(label) expression, e.g. :level.green :msg.grey
    3. The :msg flag now support numbers for express the message of the correct index, e.g. :1.green :2.grey, and you will get an green 'hello' and a grey 'world' by using logger.info('hello', 'world'). Remember, the index start from 0.

    0.3.2

    1. User can redefine color and level prefix by set the color and level property of each method.

    4. Add error as alias of err, warning as alias of warn
